Microsoft today officially began rolling out its Windows 10 operating system. If you've reserved your upgrade, it won't be long until you can use the new OS.

We've been watching the development of Windows 10 since Microsoft shared the strategy and new features behind the operating system during a media event in January. We've read the developers' blog posts, downloaded the preview builds, and watched the OS take shape.
